Geotextile is a part of technical textile which is used for special purposes. Geotextiles form one of the two largest groups of Geo synthetics. The raw material of geotextile comes from polyester, Polyamide, Polypropylene and Polyethylene. The application of geotextile is civil engineering, coastal engineering and also huge used of construction site.  Generally geotextiles are located in the tension area to make stronger the soil. Now I would like to discuss the classification of geotextile.

The Classification of Geotextiles:

Geotextile is divided by two ways. They are-

  1. According to Time of Use
  2. According to Method of Production

    Jute Geotextile

 1. According to Time of Use: 

1st Generation:

 Geotextile that were being manufactured for another purpose, such carpet or industrial sacking, but later used for geo technical purpose are known as 1st generation geotextile.

2nd Generation:

Geotextile that were manufactured for certain geo-technical purpose, but without adopting modern technology.

3rd Generation:

Geotextile that was manufactured, designed, and produced to meet certain end use. It is actual geo-textile.

2. According to Method of Production:


These were produced in various types of loom. However, these were categorized as lighter geotextile and heavier geotextile.

Heat Bonded Non-woven:

These geotextiles normally made from continuous filament fine fibers that has been laid randomly onto a moving belt and passed through the heated roller system when a thin sheet of textile is obtained.

Needle Punched Non-woven:

These types of geo-textiles are made from a blended web of continuous or staple filament that is passed through bank of maple reciprocating bearded needles. In case of needle punched non-woven geotextile, the GSM can be found upto 2000 which is too higher than heat bonded non-woven geo-textiles.

Knitted Geo-textiles:

Knitted geotextiles are normally restricted to warp knitting. These are normally used fine filtration, soil reinforcing grids etc.


Thus, the need of textile goods in the fields mentioned above has been stressed and their role in the reduced usage other material rather than textile and textiles prove to be flexible in their suitability for specific geographical locations. So now it is our turn, to carefully and beautiful shape this infant technology, to contribute to the nation’s economy.
